Prepare the peppers. Slice off the top and clean the insides.
Heat a splash of olive oil in a saute pan.
Saute the onion until soft, then add the garlic. Cook for a minute.
Add the ground meat. Season with salt and pepper. Break the meat apart with a wooden spoon and cook it until it starts to brown.
Stir in the rice and tomato paste. Drop the heat to low. Cook for a minute.
Pour in the hot water or stock. Cook over low heat, uncovered, until the water has completely drained.
Add the paprika, cumin, oregano, pine nuts, parsley, and grated tomato pulp. Stir to combine. Taste to see if the filling needs any additional seasoning.
Preheat the oven to 200°C / 400°F.
Stuff the peppers with the filling and close them with their lids.
Place them in a baking dish or pan (I used a 9 x 13-inch pan / 23 x 33 cm).
Add the potato wedges all around the peppers.
Stir the 1 tablespoon of tomato paste into 1½ cups of hot water. Pour this into the pan.
Drizzle with the 6 tablespoons of olive oil.
Season the potatoes and the peppers with salt, pepper, and 1 teaspoon dried oregano.
Cover the pan with parchment paper and with aluminum foil. Or with its lid if it has one.
Bake for 1 hour, then uncover the pan and bake for another 15 minutes. If necessary, add a splash of water when you uncover the pan.
Let the food sit for 30 minutes before serving.
Serve the peppers alongside the potatoes with a large piece of feta cheese if you like!
